- mobile phones and other wireless devices are also used for data services such that data is retrieved from a data provider via e.g. mobile communication network.
- a data provider via e.g. mobile communication network.
- a mobile phone can run a mobile web server, the content of which can be made available to virtually anybody who has access to the internet.
- the content of the mobile web server is accessed from the internet via the mobile communication network, to which the mobile phone or other wireless device that is running the mobile web server is attached, typically through a web gateway.
- the gateway can e.g. provide the mobile web server related connectivity and security functions.
- the web gateway can receive HTTP requests directed to the mobile web server and relay the requests to the mobile web server using an address of the mobile web server in the mobile network that is known to the gateway.
- the gateway can also operate as a firewall.
- a user of a mobile phone with a web browser can access the content of a mobile web server run by e.g. another mobile phone in a similar manner as accessing the content of a web server in the internet. That is, the user enters or selects, using the web browser of the mobile phone, the URL (Uniform Resource Locator) associated with the mobile web server, after which the protocol stack software of the mobile connects the mobile phone to the mobile web server and retrieves the requested content.
- the URL Uniform Resource Locator
- the data communication path between the mobile phones may run a long distance in the network infrastructure of the mobile communication network and reserve two uplink and two downlink channels in the cell where the mobile phones are located.
- a similar situation may arise when the mobile web server is accessed e.g. from a laptop computer.
